COLOR 0R I'NK PAD'Q SPECIFICATION forming part of Letters Patent No. 351.928, dated November 2, 1886.

Application filed May 6, 1886. Serial No. QOLQ'IT. (Nomodel Be it known that I, Josnrn B. LAUGHTON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Color or Ink Pads, of which the following is a specification.

My invention relates to ink or color pads, such as are employed for inking hand-stamps and the like, and has for its object to provide pads of this character contrived in better form for containing and yielding the ink, and having a case adapted for protecting them from the dust while not in use without interference.

with or detriment to the hygroscopic properties of the pad, to prevent the drying and hard ening, as the common pads do when closed over night, and to avoid the care and trouble of so frequently renewing the ink or solvent substance- Theinvention also comprises a simple contrivance for securing the pads in the inclosingcase, all as hereinafter fully described, reference being made to the accompanying drawings, in which-- 7 Figure l is a pcrspectiveview of my improved pad with the c'overof the case raised, and Fig. 2 is a longitudinal section, the case being closed. l

I useany approved kind of textile ink-pad, a, in two plies, as represented in Fig. 2, of which the lower one is preferably of softer texture, and iswholly, or to the greatest extent, charged with the ink or coloring-matter,

and constitutes what I call the container, and the upper one is mainly charged with glycerine and alum or other solvent, and serves to pump the ink, so to speak, .up from the container by capillary action, and by the effect produced by the pressure of the stamp and the recoil of thefibers when the stamp is removed; but instead of thesingle-felt plies, two or more layers of woven fabric sewed together may be used for each ply. I prefer, however, to use the felt and to apply the color to they lower one, as above stated, and I make the application by preparing the ink in a paste and pressing it by rolls or other means into the pad, which, with the upper pad charged with the solvent, is an arrangement affording much greater durability, and being more efficient and economical. The ink is applied to the stamp more, evenly without oversupply, the stamp prints without blotting, and the print dries quicker, and is less liable to be smeared or blurred. The pad also retains the ink better, giving it almost entirely by pressure, and but slightly by rubbing on the surface.

However the textile portion of thepad is constructed, I arrange it ina case, b, of tin or other approved material, having a cover, c,to close it for excluding the dust when the pad is not in, use, and I construct the case with any approved form of open passages,d, through the sides and ends for the circulation'of air, in order that the process of absorption of moisture from the air may continue all the same when the box is closed,"by the glycerine or other solvent of the ink contained in the feeder, whose surface is exposed to the air, so that the ink will be in fit condition for use when the box is opened. The advantage of this arrangement for admission of the air, instead of leaving the box open, is that the air flowing in through the sides will be comparatively free of dust, because of the settling of the dust down from the horizontally'flowing currents entering the passages, so that but very little dust enters the box, whereas the open box is best adapted for the settling of the dust into it from directly over, and also from much of the space around about, from which the varying currents gather and deposit it in the box. Thus it will be seen that while with an ordinary case the.

pad is greatlyinjured by thedust if left open for enabling the collection of moisture from the atmosphere to continue when not in use,

p and it dries quickly and needs much care and troubleto keep it in good condition if the box be closed when not'iii use for excluding the dust, with my improved case all the advantages of the open condition for the absorption of moisture are available with almost entire protectionfrom dust.

The paste may consist of any approved ink or color composition. Starch and sugar may be employed for absorbing andthickening substances, together with the pigments and solvent substances, and the paste may be pressed into the textile padby other means; but 1 prefer to use rolls adapted to compress the paste into the fabric by running it with the paste applied to the surfaces between the rolls.

The top layer is charged with glycerine and alum for an absorbent of moisture and feeder of the same to the container or under layer. It is also a distributer of color from the con tainer to the type through pressure of it by they can be readily pulled from under thelips,

and be readjusted under them when it may be required; but any other approved means of fastening these parts of the pad may be employed.

\Vhat I claim, and desire to secure by Letters Patent, is-

.1. Theiniproved inking pad for handstamps,eonsislingofatextilecontainercharged or incorporated with ink or color-paste by compression, in combination with a super imposed textile feeder charged with a hygroscopic solvent, substantially as described.

2. The combination of an inclosing-case having a cover, and constructed with openings through the sides for the circulation of air laterally through the case,with an inking-pad for hand-stamps, consisting of a textile con- 0 tainer charged or incorporated with ink or color-paste by compression, and a superposed feeder charged witha hygroscopic solvent, substantially as described.

3. The combined ink or color pad and an 5 inclosing-case therefor having a cover, and constructed with openings through the sides, and having the pads secured by the lips cut for the openings, substantially as described.
